How to care for goldfish

Goldfish or goldfish is a more common fish species in all fish tanks. The carp was one of the first fish domesticated in the world for human consumption. This kind of fish varies in coloration, size and shape.

It is one of the longest-lived freshwater fish. This fish can live up to 8 years and can grow up to 20 cm if well cared for. It is relatively easy to take care of this species so in this post I bring you some tips so that they can live a long time.

Aquarium requirements

The first thing you should know is that the tank should be large, approximately 35 liters per fish. If kept in confined spaces, they will not reach sexual maturity. These fish can live in small spaces but will not live comfortably and will not reach sexual maturity.

The aquarium tank must have sufficient light, these animals are diurnal so they need a light cycle to keep them active during the day and a dark cycle for them to rest at night. If these requirements are not met, the fish will lose its natural color.

The water temperature should be between 16 and 24° C. There are a variety of thermometers available on the market to measure the temperature. The water should be changed every week, you can change an equivalent of 20% of the water in the tank or 100% of the water, depending on the decoration of the tank.


You can purchase fish food at pet stores. These fish are big eaters so care must be taken not to overfeed them. Feed them once a day with goldfish food and they will devour them in a minute. It is advisable to remove the rest of the food that remains floating.

Goldfish are omnivorous, i.e. they eat vegetables, cereals and dogs. One of the foods that can be given are peas, lettuce, broccoli, worms, mosquito larvae, among others. It’s all a matter of getting them used to eating different foods.

Common disease

One of the most common diseases in this type of fish is white spot. This is a parasite that lodges in the scales and fins. To identify it, observe your fish, if it has white spots on its body, it is because it suffers from this disease, which is curable. By simply isolating the fish and treating the tank for a few days, your fish will be cured.

One way to kill the parasite is to raise the water temperature and add salt to the tank. Another way is to put fungicide in the water of the tank where the Goldfish is kept.
